Specification of Letters Patent.

Patented March 27, 1906.

Application filed October 31, 1904. Serial No. 230,740-

TO (oi/Z whom it may concern:

Be it known that I, CHARLES DACKIEWIOZ, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented a MechanicalMotor, of which the following is a specification.

My invention, comprising an improved mechanical motor, consists of anapparatus in which the weight of a falling body arran ed to follow ahelical guide or track is utilized to transmit rotative movement to ashaft.

My invention is fully shown in the accompanying drawings, in whichFigure 1 is a perspective view of a structure embodying my invention.Fig. 2 is a sectional view taken on the line a a, Fig. 1. Fig. 3 is anenlarged sectional view taken on the line b b, Fig. 1 and Figs. 4, 5,and 6 are views illustrating modifications of my invention.

This device has been employed as a motor for operating clock-movements,although it may be used as a prime mover for operating The arrangementof the apparatus is such that motion will be maintained for a long time,the pitch of the helical guides or tracks, the angle at which they aredisposed, and the weights being so proportioned that the rotativemovement is comparatively slow.

In the accompanying drawings, 1 repre sents the central stem of themotor structure having on opposite sides helical guides or tracks 2, sodisposed as to cause the round bodies 3, arranged on the same, to traveltoward the center of rotation, such bodies in turn causing thetrack-carrying structure to rotate. The tracks are of uniform pitch, theinternal diameter of each one being the same, and the surface receivingand supporting the spherical weighted bodies is concaved, as clearlyshown at 4 in Fig. 3. The lower end 5 of the central stem may bepointed, as shown, to reduce friction as it rotates and is mounted in astep-bearing 6. The upper end 7 of the central stem is mounted in abearing 8 and is provided with a bevel-wheel 9, whereby the rotativemovement of said stem may be transmitted to the point of use. In thepresent instance I have shown a shaft 10, suitably mounted and having abevel-pinion 11, meshing with the bevel-wheel 9.

The helical tracks 2, disposed on opposite sides of the central stem 1,have portions in engagement with said stem in a plane at right angles tothe line drawn through the axis of rotation, the balls being disposed ina horizontal plane. It will be observed, however, that such arrangementis not essential, as no matter where the convolutions of the helicaltrack-may be the balls will always find a point of relative rest in ahorizontal plane.

To rotate the central stem 1, the weights 3 are provided, indicated inthe drawings as being within the helical guides or tracks, which aredisposed on opposite sides of said central stern, and these weights arepreferably spherical, so that they may follow the helical tracks withthe least resistance. Owing to the weights carried thereby and beingsupported at an angle, the stem carrying the helical tracks has aconstant tendency to turn or rotate, and this movement, acting throughthe gears 9 and 11, causes the shaft 10 to rotate. As the track-carryingstructure rotates the portions of the tracks immediately supporting theballs tend to maintain a hori zontal position, said tracks beingconcaved so that the balls can always find a point of rest, and inconsequence said balls are constantly changing their position withrelation to said helical tracks as the latter turn or move with thecentral stem on the axis of rotation. As said weights move along thesetracks the pitch of the latter tends to alter the point of applicationof their weight, so that each ball moves in one direction, and under theinfluence of the force of gravity they act against the helical tracksand rotate the central stem carrying the same. The movement of thisstructure is relatively very slow and permits the balls to alter theirposition so gradually that they are never displaced and gradually reachthe bottom of the helical path or track, driving with uniform regularitysaid track-carrying structure and through it the clock escapement orother apparatus. The structure shown in the drawings herewith isrelatively small, and in practice helical guides or tracks having threeor four times the number of turns would be employed. The weights wouldtherefore require a longer time to reach the bottom of the tracks andthe rotation of the stem 1 would be correspondingly increased. The angleat which the stem carrying the helical tracks is disposed determines thespeed of rotation, and in order that this speed may be as slow aspossible the stem 1 should be arranged at as small an angle to thehorizontal as will maintain the speed desired.

While I have shown a central stem having a pair of helical guides ortracks, it will be understood that I may employ a single helical guideor track, as shown in Fig. 4, or more than two disposed around a centralstem, as shown in Fig. 5, either structure having the spherical weightor weights and operating in precisely the same manner as the structureshown and described herewith, and in some instances I may dispose a pairof helical tracks at an angle to each other, as shown in Fig. 6, havingmeans whereby their independent movement may be transmitted to a singleshaft. A single structure, such as shown, is preferred, however, asfriction is thereby greatly reduced.

Both balls or weights are preferably introduced at the same time, sothat their movement is coincident, each weight therefore in actingagainst the pitch of the helical guide or track overcoming the other andcausing the force of gravity to be transmitted by said helical guides ortracks to the central stem 1 and transformed into rotary motion.

Having thus described my invention, I claim and desire to secure byLetters Patent 1. A mechanical motor comprising a stem or shaft mountedso as to rotate, a helical track carried thereby and moving with saidstem, and a freely-movable weight resting on said track and serving torotate the stem or shaft, the track and weight partaking of suchrotative movement.

2. A mechanical motor comprising a stem or shaft mounted so as torotate, helical tracks carried thereby and moving with said stem, andfreely-movable weights mounted upon said tracks and exerting their powerthereon to rotate the stem or shaft, the tracks and weights partaking ofsuch rotative movement.

3. A mechanical motor comprising a stem or shaft mounted so as torotate, helical tracks carried by said stem, said tracks having theirpitch disposed toward the axis of rotation and moving with said stem,and weights adapted to move along and with said tracks and rotate thestem or shaft, the tracks and weights partaking of such rotativemovement.

4. A mechanical motor comprising a stem or shaft mounted so as torotate, a pair of helical tracks carried by said. stem or shaft anddisposed opposite each other with their pitch inclined toward the axisof rotation, and weights adapted to said tracks, said weights in movingtending to displace the helical tracks and thereby rotate the stem orshaft carrying the same.

5. A mechanical motor comprising a stem or shaft mounted so as torotate, a pair of helical tracks carried by said stem or shaft anddisposed opposite each other with their pitch inclined toward the axisof rotation, said tracks having concaved faces, and weights adapted tomove along said tracks, said weights tending to displace the helicaltracks and thereby rotate the stem or shaft carrying the same.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
